TYPOGBAPHIGAL SLUG-CASTING MACHINE.

Application vfiled November 13? 1926.V Serial No. 148,304.

My invention relates to means foi` insuring a reliable delivery from their mold of type'- slugs as castby machines of the linotype class, In suchl machines the mold is mounted in a rotatable carrier which positions the mold in an upper horizontal position to receive the cast of metal and thereafter carries the mold to a vertical position where it is held stationary and the slug ejected therefrom between trimming knives and `thence into a receiving `and assembling tray usually calle-d a galley. This galley is positioned either vertically or angularly according to whether the machine on which it is mounted is intended to be used only for producing short news7 slugs or for producing slugs of miscellaneous lengths and thicknesses. When Y the galley is mounted angularly the slugs therein are visible tov an operator forpurposes lof inspection, but their delivery to'and into the galley is unreliable and annoying. My present invention is directed to improv ing the delivery of the slugs into a galley thus singularly -mountedg and .also to providing for the employment of two galleys on the same machine forselective use according to the length, quantity or character of slugs being produced and the preference of an operator. The structure and mechanism involved in'attaining this objective is illustrated in the accompanying drawings, in

' which- Fig. l'is a front elevation of the slugcasting portion of linotype machine, showing both a vertical and an angular galley in their position relative to the mold and rtrimming knives and the slug-delivery channel leading therefrom. In this view the slug-delivery channel is in position to deliver slugs to the angular galley.

Fig. 2 is a replica of a portion of Fig. 1 except that the slug-delivery channel is shown adjusted to permit the delivery .of Shins into the vertically-nlounted galley# Fig. 3 is a leftfhand view of Fig. 1.

Figj is a view ofthe slug-delivery channel on the linee-.4. of Fig. 1.

lr eretofore the galleys of either form have been held Stationary and the slugs'pushed into them by the end of a leverV mounted Similarly t@ the galley-Suprftns lever A of this invention. The result has been that the slugs would frequently strike this pusher before'or instead of entering the galley. Hence l eliminate this pusher and render the galleys movable longitudinally in lieu thereof. vReferring first tothe slug-delivery channel B: The channel proper B1 thereof serves only for delivering slugs to thel angular, or lower, galley C., and for such purpose is moved to the left on a pivot-shaft D, thus placing the channel'B1 in front of the mold slot E from which the slugs are ejected. vIt is held in this left-hand lposition lwhen a right-hand slot B3 is made "to engage a stud F1 in the machine frame F. When the lefthand slot Bf is engaged with the stud F1 the channel B as a whole' is moved from in front of the mold slot to permit the slugs to' enter on the vertically-m ounted, or upper, galley ,GQ The slots 133,134tv are through an exten sionB irom the inner side wall Bfof the channel B1, 'and -the channel is pivotally movable on its shaft D for the purpose of engaging and disengaging the slots from the stud F1.Y The vchannel B1 is provided ywith a yfloor B7 which terminates flush with the floor of the lower galley C yand on this floor the slugs are supported as they yslide from between the trimming knives (not shown) through the channel-and into the lower galley. The outer wall B2 of the channelextends beyond the inner wall andl the floor thereof and yacross thefloor of the galley, and provides an abutment against which the. slugsS are stopped when'the galley moves vlo.ngitudinally to the right as indicated in dotted lines in Fig. 1. Whenlthe galley thus moves to the right the slugs therein will be packed against the wall '13?, andY when it moves to lthe left the slugs will becarried therewith7 thus," leaving a space between the last, orA end, slug andthe wall B2, andinto this spac'eg the slug next ejected will enter. rlhe movement of the galley is repeated each time a slug enters therein, and for the purposeof such movement is indirectly'mounted at its right-hand end on the upper arm H1 Iof a crank-like lever'H thepivot end Hzfof which has abearing in the frame F; and at itsy left-hand end it is indirectly supported on the lower arm'I1 of a swinging lever I having a vpivoted bearing` in a Vbracket J. secured tothe frame F. .The galley C is removably and directly supported on a bracket K` pivdtally supported at its (opposite ends Y on the'swinging horizontalarmsr H1 and Il of the levers'H and I respectively. The gal- Of the angulares tiene@ H and I f ley moves to the Vright by gravityy by lreason relative to the perpendicular, andis returnedto the left by means of a cam L rotatable incidental to the normal rotation ot a mold-carrier driving-pinion M with which it is integral. For the purpose ot' imparting movement to the galley C, connection between the cam L and the swinging lever l is established by means of an arm O rigidly ksecured to the lever I. Since the pinion M rotates four times incidental to a rotation ot' the mold carrier N-each time a slug is cast, and since two reciprocations or' the galley C are considered sufficient to move the slugs therein as explained, l provide clearances P1 and P2 on the usual irst elevator P, and extend the arm to engaging relation with the elevator P. Thus, when the elevator P is in its down position the clearance P1 will permit .a movement of the Vgalley C preliminary to the deposit of a slug therein7 and when the elevator P .is in its highest position the second clearance P2 will permit a second movement o't the galley following the entry of a slug therein. Between the clearances P1 and. P2 an anti-friction roller O1 on the `arm O engages thev full surface P3 of the edge of the elevator -P and thus holds the galley stationary during two rotations of the pinion M. y t

The upper galley Grhas a reciprocating movement similar to that described for the lower galley and under control of the same mechanism, bot-h galleys moving together whether in use or idle. WThen the upper galley is idle asa slug-receiver it is adjusted to theleft in order to permit the channel B to be positioned to the lett in front of the mold for conducting slugs to the lower galley. F or the purpose of such adjustment the upper galley is provided with two studs G2, G2 either of which may be made to engage a notch O2 in an angle O3 of an extension O4 from the armv O. At its lett end the galley G issupported on the arm extension O4 and at its right end is suspended on a swinging link Q, hence by seating the left-hand stud G3 in the notch O2 the galley is rendered operative, and by seating the right-hand stud G2 in the notch the galley is adjusted to inoperativev position. But in either positi on the galley Gr has a reciprocating movement with the arm O, and this movement of vthe galley when inoperative as a slug-receiver is utilized to cause aniabrupt and precipitous drop of the slugs into the channel B1 in order that they may acquire suticient momentum to carry them dependably to the lower galley. Vith this object in yview the floor G1 of the Lipper galley is made to clear through a notch B2 in the inner wall Bof the channel B and to extend across the path of the slugs regardless of the adjustment of the `galley G; hence whenl slugs destined for the lower galley emerge from the mold and trimming knives, they are momentarily supported on the end of the floor G1, and as the upper galley reciprocates to the lelt the slugs are scraped from the floor G1 against the inner channel wall B6 and drop abruptly throughv the channel to the lower galley. lVhen the upper galley G and channel B are adjusted to the vlett as in Fig. l, the` reciprocating movement of the upper galley to the right will place thefloor G1 thereof in about the position shown in Fig..2, relative tothe mold, and when retracted to the lett the ioor will move from in iront ot' the mold and out of the channel B1, permitting the slug to drop. In Fig. 2

the elevator P is in raised position with theY anti-friction 'roller O1 occupying the depres-A sion P2, therefore the galleys are moved to the right; and since t-he channel element B isalso tothe right invFig. 2, therefore when the galleys are retracted to the position shown in Fig. l as the elevator descends, the floor G2 of the upper galley will move from the channel B1 and the slug which hasloeen deposited thereon will drop tothe lower galley.v

TWhen the upper galley Grv is operative to receive slugs, the channel B is adjusted to the right as in Fig. 2 and the slugs are ejected directly to a position on the floor G1 of the galley. As controlled by the clearance P2, the galley G then moves to the right and the slugs therein are packed against the outside of the inner channel wall B6; andl when the galley moves to the left the slugs therein are carried therewith, leaving space between the end slug and y the wall B6 `for the entry ot a succeeding slug. Y

Having thus described my invention and the advantages' of its use, what I claimas new and desire to securefby Letters Patent,

1.- n a slug casting machine, a slug receiver having af reciprocating movement -for the purpose of advancing the slugs thereon step by step as they enter therein. l Y

2. In a slug casting machin-e, a reciprocating slug receiver and a relatively stationary abutment across the receiving thereof, whereby successive movements of said receiver in one direction will pack the slugs therein against said abutment and successive movements thereol` in the opposite direction. will move the slugs therein away A'fromv said abutment and thus providespace for the successive entry of slugs into said receiver.

3. In a slug casting machine, in combination with a moldv in which slugs arercast, a slug receiver mounted angularly below said mold, and a channel throughwhichslugs are conducted 'from said vmold to saidV receiver, means for causing the slugs to drop precip- -itously into and through lsaid channel, said means being av slug-support automatically movable to and retractable from a position across said channel in front of said mold,

whereby slugs are momentarily retarded on said support and drop into said channel when said support is retracted.

4j. In a slugcasting' machine, in combination, a mold from which slugs are ejected, a slug' receiver mounted vertically in a plane in front of said mold and a slug r ceiver mounted angularly in a plane below said mold, a channel 'for conducting slugs from said mold to said angularly-mounted receiver, and means whereby either of said slug receivers may be used, selectively, said means consisting in rendering said channel adjustable to a non-interfering position Whensaid vertically mounted receiver is in use, and in rendering?,- said vertically-mounted receiver adjustable to a non-interfering position when said channel and said angularlymounted receiver are in use.
